Step by step
How it's done while you train
Step 1 of 7
Step 3 of 7
Set the altitude you want to simulate and watch how the lever (1, 2 or 3) and the power ball move into place.
Equivalent to: Sierra Nevada (CAR) · 2,320 m
Ideal for sleeping in a tentHypoxia during sleep: more haematocrit, VO₂max and capillarisation.
Approximate values (tolerance ±2 %). The simulated altitude adds to the real altitude where you are: 2,500 m simulated in a town at 500 m is about 3,000 m for your body.

Approximate simulation. Everyone responds differently: we adjust the altitude with you so that during sets you're between 80 and 85 %, and above 90 % when recovering.
What you get
What changes in your body and what the science says
In 2019 the Nobel Prize in Physiology recognised Kaelin, Ratcliffe and Semenza for discovering how our cells sense oxygen and adapt when it's scarce, through the HIF factor. It's the same mechanism that kicks in when you train with the mask.

What each type of hypoxia boosts
The three forms of hypoxia work on the same body, but each one puts the focus somewhere different. We only show the improvements backed by science for each type. Choose the type of hypoxia and tap each improvement to see the study and the body system involved.
Loading 3D body…
Sleeping at altitude is a very powerful stimulus: we adjust the protocol and your training loads so you don't build up fatigue in the central nervous system.
Approximate scale based on studies with athletes and on our experience; the figures for each improvement come from the cited study. Response varies from person to person. Anatomical systems: Z-Anatomy and BodyParts3D (CC BY-SA 4.0).
Who it's for
It works for you if…
Endurance sportsCycling, running, triathlon: more VO₂max and more watts without adding training hours.
High-intensity effortsCrossFit, HYROX, team or combat sports: you repeat sprints and last longer in the final effort.
You compete at altitudeTrail, skiing or mountaineering: you arrive pre-adapted for the race or the expedition.
How we get started
You're never on your own, not even for a day
Behind every session there's a person from our team looking out for you. We set up the equipment with you, design your plan and review your sessions so that every day you breathe the right altitude for you.
- Personal advisor
- First month of follow-up free
- By video call and app
Initial video call
A person from our team talks to you face to face: you set up the equipment together, we configure everything and we find, live, the altitude you respond well to.
Your plan, tailored to you
We set your goals, design your calendar and periodisation, and share the hypoxia protocols that work best for what you're after.
We analyse your sessions
We review the report from each session in the pulse oximeter app and message you on WhatsApp to adjust the altitude. The first month is free, and even daily if you need it.

Safety
Always under control
- Pulse oximeter with alarm, always required. Set to 80 %: if your saturation drops below that, it alerts you.
- You work to a target saturation. Not a fixed altitude: that way the dose adapts to how you are that day.
- Warm up and finish without hypoxia. The mask is used in the main block; the warm-up and cool-down are done with normal air.
- If you're tired, unwell or not properly recovered, skip that day. And if your saturation drops below 75 %, stop the set or lower the altitude.
Our equipment is for sports and wellness use. If you're unsure whether hypoxia training is right for you, talk to your coach or an altitude training professional.
FAQ
What we're asked most
How long does a session last?+
Between 50 and 70 minutes: about 15 minutes of warm-up, the main block of sets with the mask and a 10-minute cool-down.
How many sessions a week?+
Usually two days a week, whichever you choose (for example Tuesday and Friday). We fit them into your training calendar.
What can I train on with the mask?+
On any stationary machine: turbo trainer, spin bike, treadmill, elliptical or rower. The generator sits next to you and the tube reaches the mask.
What kind of sets do you do?+
For example, 4-minute sets at 85 % of your maximum heart rate, or blocks of short 10-second sprints. We give you the protocol that fits your sport.
What if my saturation drops too low?+
The pulse oximeter alerts you with its alarm. If you drop below 75 %, stop the set or lower the altitude; within seconds you're back to normal values.
Can I combine it with hypoxia at rest?+
Yes. It's the same generator: you can do sessions at rest on rest days and during exercise on training days. See hypoxia at rest →
